As can be seen, the only portions of the loading ramp 10 to that touch vehicle tailgate 16 are foam layer 103 of lip member 26 and end wall 112 of bumpers 28. Both the foam layer 103 and bumpers 28 are configured to prevent damage to the painted surface of tailgate 16 to avoid damage to factory finishes applied to tailgates of motor vehicles.

Loading ramp 10 includes a pair of elongated side rails 12 that extend from ground level surface 14 to tailgate 16, as shown, for example, in FIG. 1. While loading ramp 10 is manufactured from aluminum in accordance with the illustrative embodiments, other suitable metallic, non-metallic, and composite materials may also be used. Each side rail 12 includes a boxed portion 34 having a top wall 36, an opposing bottom wall 38, and first and second side walls 40, 42, as shown, for example, in FIG. 7.

Each side rail 12 includes a lip member 44 that extends along the length of boxed portion 34, as shown, for example, in FIG. 2. Lip members 44 provide support for cross members 20 and end support member 24. Cross members 20 and end support member 24 are secured to lip members 44 by welding. It is contemplated that other suitable securing means can also be used including riveting, epoxy, bolts, or other fasteners.

Each side rail 12 is also formed to include a cavity 43 that is defined by the walls 36, 38, 40, 42, as shown, for example, in FIG. 7. Each cavity 43 located at the upper end 30 of side rails 12 is adapted to accept a bumper 28, as shown, for example, in FIG. 9. Bumpers 28 are configured to prevent side rails 12 and end support member 24 from contacting tailgate 16 of motor vehicle 18. Each side rail 12 also includes a guide member 48, as shown, for example, in FIG. 7. Guide members 48 extend from edge 46 of top wall 36. Guide members 48 extend along the length of each side rail 12 to assist in guiding equipment over loading ramps 10 to prevent equipment from falling off of loading ramps 10.

Cross members 20 are oriented perpendicularly to side rails 12 and are adapted to provide a support surface to support equipment being transported over vehicle tailgate loading ramp 10. Each cross member 20 includes a first end 64 and a spaced-apart second end 66, as shown, for example, in FIG. 4. Ends 64, 66 are designed to rest upon lip members 44 of elongated side rails 12. While the cross members 20 are manufactured illustratively from extruded aluminum, other suitable materials may be used, including composites, polymers, and other metals. Cross members 20 are secured illustratively to lip member 44 and side wall 42 by use of welding or other suitable means such as fasteners or epoxy.

Cross members 20 include a first inclined side wall 68 and an opposed second inclined side wall 70, as shown, for example, in FIG. 6. Cross members 20 also include a top wall 72 and an opposed bottom wall 74. Side walls 68, 70 of cross members 20 are configured to permit a wheel from an ATV, motorcycle, or lawn tractor to transition from a first to a second cross member 20 when traveling over loading ramp 10.

In order to increase traction, each of the inclined side walls 68, 70 include traction ribs 76 that extend along the length of the cross members 20, as shown, for example, in FIG. 6. Cross members 20 also include raised edges 78, 80 that are raised above top wall 72. Traction ribs 76 and raised edges 78, 80 allow the wheel of an ATV or lawn tractor to engage cross members 20 without slipping. Cross members 20 are welded along first and second side walls 68, 70, to side wall 42 of side rail 12 and, if necessary, along edge 82 of elongated lip 44 and bottom wall 74 of cross member 20. Cross members 20 are spaced close enough together so that a standard ATV or tractor tire traveling along the length of loading ramp 10 contacts an adjacent cross member 20 before leaving the previous cross member 20 when moving across ramp 10.
